The site was identified as important in 1998 because it was regularly supporting significant populations of the species listed below, meeting ('triggering') IBA criteria.

Populations meeting IBA criteria ('trigger species') at the site:

Species	Red List1	Season	Year(s)	Size	IBA criteria
Burchell's Sandgrouse Pterocles burchelli	LC	resident	1998	present	A3
Barred Wren-warbler Calamonastes fasciolatus	LC	resident	1998	present	A3
Burchell's Starling Lamprotornis australis	LC	resident	1998	present	A3
Kalahari Scrub-robin Cercotrichas paena	LC	resident	1998	present	A3
Sociable Weaver Philetairus socius	LC	resident	1998	present	A3

1. The current IUCN Red List category. The category at the time of the IBA criteria assessment (1998) may differ.

Ideally the conservation status of the IBA will have been checked regularly since the site was first identified in 1998. The most recent assessment (2014) is shown below.

State (condition of the trigger species' habitats)
Habitat	Quantity (% remaining)	Quality (% carrying capacity)	Result
Desert	good (> 90%)	good (> 90%)	favourable
Forest	good (> 90%)	good (> 90%)	favourable
Savanna	good (> 90%)	good (> 90%)	favourable
Wetlands (inland)	good (> 90%)	good (> 90%)	favourable

Pressure (threats to the trigger species and/or their habitats)
Threat	Timing	Scope	Severity	Result
Climate change and severe weather	likely in short term (within 4 years)	whole area/population (>90%)	slow but significant deterioration	high
Biological resource use	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Human intrusions and disturbance	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Invasive and other problematic species and genes	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Natural system modifications	happening now	some of area/population (10-49%)	slow but significant deterioration	medium
Transportation and service corridors	happening now	small area/few individuals (<10%)	slow but significant deterioration	low
Energy production and mining	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low
Pollution	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low
Residential and commercial development	happening now	small area/few individuals (<10%)	no or imperceptible deterioration	low

Response (conservation actions taken for the trigger species and/or their habitats)
Protected areas	Management plan	Other action	Result
Whole area of site (>90%) covered by appropriate conservation designation	A comprehensive and appropriate management plan exists that aims to maintain or improve the populations of qualifying bird species	The conservation measures needed for the site are being comprehensively and effectively implemented	high
